A world health organization core drug use indicator based prescription study in the dermatology outpatient department of a tertiary care teaching hospital of central South India

Background: Irrational prescribing is a universal problem that may lead to inadequate response to medication therapy, poor patient compliance and increased adverse drug reactions ultimately leading to frequent hospital admissions. Hence this study was done to assess the drug utilization pattern using WHO core drug use indicators so that the recommendation can be made towards the rational prescribing.Methods: A sample of 3650 prescriptions was analysed prospectively to assess the drug utilization patterns in the dermatology OPD of a tertiary care teaching hospital of central south India.Results: The average number of drugs per prescription was 2.74 whereas 79.26% drugs were prescribed by generic names. Percentage of encounters with an antibiotic prescribed was 18.68%. Regarding use of injections, 3.26% prescriptions contains one or more injections. Percentage of drugs prescribed from essential drugs list was 78.37%. Average consultation time was lower (2.9 minutes) than recommended.Conclusions: The data from the present study indicates that prevalence of polypharmacy, inadequate consultation and dispensing time along with poor patient’s knowledge are the areas of medication therapy to be improved. Availability of essential drugs and key drugs in stock should be improved to achieve rational therapeutic goal. Further, continued medical education regarding the rational prescribing will definitely improve the standards of health care delivery

AMELIORATIVE EFFECTS OF PHYTOANDROGEN AND ANTIOXIDANT ON HISTOARCHITECTURE OF PERMETHRIN INDUCED CHANGES IN GOAT TESTIS

Objective: Protective effects of Tribulus terrestris (TT) and vitamin C were studied against permethrin induced changes in the histoarchitecture of goat testis.Methods: Hydroalcoholic extract of the fruits of Tribulus terrestris was prepared by maceration method and the extractive value was calculated. Fresh stock solution of permethrin (1mg/ml) in dimethyl sulphoxide and Tribulus terrestris (1mg/ml) in distilled water were prepared. Testicular tissues were cultured in TCM-199 nutrition media at 39℃ with 95% humidity and 5% CO₂ in the CO₂ incubator. Cultured testicular tissue was grouped as control having only the nutritive media, experimental group I(EI) received two doses of permethrin (100µg/ml and 200µg/ml), experimental group II(EII) was administered doses of permethrin along with vitamin C(0.1µM/ml) and experimental group III(EIII) was supplemented with doses of permethrin along with Tribulus terrestris (100µg/ml). All the groups were tested for 4 hr. and 8hr. for histoarcitectural studies.Results: Histological alterations were observed such as distorted shape of seminiferous tubules, decreased luminal and interstitial space, reduction in the population of spermatocytes, spermatozoa and spermatids in treated (E1) group as compared to control group. Maximum damage was detected at a higher dose of permethrin (200µg/ml) for 8h in contrast to lower doses (100 4h and 8h). Thus, it is concluded that permethrin has both dose and time-dependent effects. Protective groups (E2 and E3) imparted ameliorative effects by reestablishing shape of seminiferous tubules, decreasing luminal and interstitial space, increased population of spermatocyte, spermatozoa, and spermatids as compared with treated groups (E1)Conclusion: It has been reported that permethrin affects male fertility by inducing detrimental changes in the structure and function of seminiferous tubules. Both vitamin C and TT have the ability to mitigate the effect of pesticide. TT shows aphrodisiac activity against permethrin induced alterations in goat testis

Effective attenuation of atrazine-induced histopathological changes in testicular tissue by antioxidant <i>N</i>-phenyl-4-aryl-polyhydroquinolines

<div><p></p><p>Some of the environmental toxicants acting as endocrine disruptors have been associated with health hazards in human and wildlife by modulating hormonal actions. Atrazine, a strong endocrine disruptor, induces detrimental effects on gonads in male and female, and causes impairment of fertility and developmental problems as well as sex alterations. Atrazine decreases the activities of antioxidant enzymes and thus responsible for oxidative stress. Natural antioxidants have shown ability to reduce/slow down the apoptotic effect of atrazine on testicular tissue. In the present study, some <i>N</i>-phenyl-4-aryl-polyhydroquinolines bearing phenolic or/and alkoxy group(s) (<b>6a</b>–<b>6g</b>) were synthesized and evaluated for antioxidant activity in four different assays. Three best compounds (<b>6e</b>–<b>6g</b>) were studied for their ameliorative effect on testicular tissue supplemented with atrazine <i>in vitro</i>.</p></div
